Embodiment Construction

[0021]Embodiments of a portable terminal device according to the present invention will be described with reference to the attached drawings.

[0022]FIG. 1 is an external perspective view of the portable terminal device according to the present invention, showing an opened stare of the device.

[0023]A portable terminal device 1 includes a first casing 12 and a second casing 13 that are formed in substantially the same rectangular shape. The first casing 12 and the second casing 13 are rotatably connected together via a hinge mechanism 14. FIG. 1 shows the portable terminal device 1 in a state that main operating keys 20 provided on the first casing 12 and a main display 21 provided on the second casing 13 are accessibly exposed. This state is referred to “an opened state” below.

[0024]At a predetermined position inside the portable terminal device 1, a sending / receiving antenna (not shown) is provided. In the portable terminal device 1, radio waves are sent and received via a base stati...

Abstract

A portable terminal device includes first input receiving unit provided in a first casing receiving input if the device is opened to expose the first input receiving unit, first displaying unit provided in a second casing turning-on if the device is opened to expose the first displaying unit, second input receiving unit receiving input if the device is closed to expose the second input receiving unit, turning-on lock unit for controlling the first displaying unit in a turning-on impossible state on the basis of a lock set instruction input received by the first input receiving unit or the second input receiving unit, and lock canceling unit for controlling the first displaying unit in a turning-on possible state on the basis of a lock cancel instruction input received by the second input receiving unit if the first displaying unit is controlled in a turning-on impossible state by the turning-on lock unit.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to portable terminal devices, and in particularly, to a portable terminal device having one or more lock functions.[0003]2. Description of the Related Art[0004]Recently, in portable terminal devices, such as mobile phones, increasing devices have multiple functions of not only voice communication but also data communication, picking up moving images, moving audio-visual functions, and access to documents and images. Hence, the portable terminal devices have been provided with various configurations putting emphasis on operationality during using these various functions. In these portable terminal devices, in order to strike a balance between the operationality, during the voice communication and the operation using operating keys, and the demand for the device miniaturizing, foldable portable terminal devices composed of two casings connected together have been provided.[0005]In foldable po...
